SHAPING MACHINE FOR LAUNDERED COLLARS.

1 Application filed March 22, 1922. Serial No. 545,761.

useful Improvements in Shaping Machines for Laundered Collars; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

- This invention relates to a machine for shaping and otherwise finishing mens stiff collars, and is particularly intended to be used in connection with a type of collar now in vogue and extensively used, in which, while the greater portion of the length of the collar is presumed to have the usual sized crease between the outer and inner folds,

this crease is replaced by a gradually increasing roll or curved bend toward the open ends of the collar.

The principal object of my invention therefore is to provide a machine by means of which not only can the sharp-edged crease be obtained, but the rolled or curved portion may be shaped as well, and which is so arranged that the roll at both ends of the collar, assuming reasonable care on the part of the operator is given to the job, will be uniform with each other, without which effect the neatness of appearance of the collar is destroyed.

Another, and very important object, is to insure that every collar will be pressed to the same extent, or to the same degree of firmness, without regard to any difference in physical strength of one operator over another, or of any variation in effort which any one operator might exert at different times.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed- These objects I accomplish by means of such structure and relative arrangement of parts as willfully appear by a perusal of the following specification and claims.

This case is a continuation of my application filed February 1st, 1922, Serial No. 533,243, the essential features of that case being here shown and described, with the addition of certain improved features.

Fig. 1 is a side elevation of the apparatus. I

Fig. 2 is an end View of the shaping or pressing block.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates a base adapted to be securely fastened on any convenient support 2 and having a standard 3 projecting upwardly therefrom.

Fixed on the standard 3 and extending preferably in a horizontal plane is a tubular arm 4 projecting well beyond the standard. On the projecting end of the arm is a removable mandrel 5. This mandrel is circular in cross section and has a gradual taper terminating in a sharp point so as to allow it to be readily inserted into the open end of the collar. The sharp point, being of such small diameter as to fit into the normal crease or down bend in the collar at the point where the rolled effect is to begin, will permit a gradual roll to be made as will appear from Fig. 1 of the drawings.

Pivoted ontoa lug 9 formed integral with the standard 3 a suitable distance below the arm 4 is a lever 10, which projects forwardly under the arm in a vertical plane therewith, and terminates at its forward end in a holder 11 in which is fixed a block 1.2, the upper face of which is grooved longitudinally as at 13, this groove conforming in size and shape to the contour of the mandrel 5, and being alined to receive the same therein, the groove being lined with felt 14 or some similar material.

Pivoted to the lever intermediate its ends is a vertical rod or link 15 similarly connected at its lower end, under the table 2, to a foot treadle 16, pivoted at one end in a bracket or bearing member 17 mounted on the floor 18 or to some other fixed member.

A tension spring 19 extends between the lever 10 and the arm 4, and acts to hold the block 12 in constant and firm engagement with the mandrel 5.

In operation the collar 20 to be formed or shaped with the rolled or curved edges is first creased as usual. It is then held in an inverted position, and the operator first depressing the treadle to bring the block 12 away from the mandrels, the collar is placed;

over the mandrel a certain distance as shown in Fig. 1, the extent of which distance is a matter of judgment and experience, and the: treadle then released. The spring 19 will then act to cause the block to raise and press the collar-edge between the block-groove and the mandrel, the. pressure thus had being uniform in all cases. The-treadlemay' thenbe again depressed, the other end of the collar inserted, and the operation repeated, the hands of the operator being free at all times for handling ofthe-collars. The sharp point of the, mandrel, 5 being substantially ofa diameter equal to that'of the normal crease ofthe collar, the roll will start with that diameter and gradually increase with the increase in the diameter of the said taperedmandreL e v I While; I. have here shown and described the arm and mandrel as-being steam-heated,

vsince-this is the common way oat doing, I have, in mind toapply anelectric heating-element: thereto, so as to heat the same electrically in the manner-of modern fla't-irons and other appliances From: the: foregoing description it;w1ll be rea'dily" seen that I, have produced suchva device as substantially fulfillsthe objects of the invention as set forth herein.

While this specification sets forthin de tail the present and preferred construction ofthe device, still in practice such deviations from such detail may be resorted to as do not form a departure from, the spirit of the invention, as definediby the appended claims. Having thus described my invention, what,

I- claim as new andcuseful and desire to secure by Letters Patent, is

1. A mandrel which is circular in cross section, such mandreljhaving a gradual'taper terminating in a sharp point which can be readily inserted into the open end of a In testimony whereoflaflix my signature.
